GTA website.

There are 4 differing messages…..privacy restriction violation, the above notification, in breech of security conventions…and u secure site server restriction url..
Bighit mailed me to say they have had a security breech….dunno …anyones guess ..
The error you are seeing is very common when a sites security certificate runs out. The security certificate is used to establish an encrypted connection between you and the website. That is the https that you see at the top left of a URL. When the certificate is out of date your browser will give you a warning and ask you if you want to continue. That is what everyone is seeing. As much as I dislike GTA, I highly doubt that the administrator there has allowed that site to be hacked. He is a rather accomplished black hat himself...
If you want to avoid that warning connect via http and not https. Your connection will no longer be secure but you won't get the warning.

Try not to believe every rumor you hear.
